Statistics CalculatorsAugust 15th, 2017
Z-scores are the way we compute normal probabilities, as any general normal distribution can always be reduced to a standard normal distribution. Check out this Z-Scores Calculator.

Cramer's V CalculatorDecember 25th, 2016
The idea of "effect size" is very relevant in statistics. If often happens that a test statistics is significant, but the association has no practical meaning. This is because a extremely large sample size alone can find significant n extremely small effect. Cramer's V is a statistic that assess the effect size or practical significance of the association between nominal variables. Check it out: Cramer's V Calculator.

Calculator of the Area and Volume of a PyramidDecember 5th, 2016
More solvers for our series of elementary geometry solvers, and we now add a calculator of the area and volume of a square pyramid that will show you all the steps and formulas used to calculate the surface area and volume of a square pyramid of side \(l\) and height \(h\).

Calculator of the Area and Volume of a CubeDecember 4th, 2016
We continue our series of elementary geometry solvers, and we now add a calculator of the area and volume of a cube that will show you all the steps and formulas used to calculate the area and volume of a cube of side \(l\).

Calculator of the Area and Volume of a ConeNovember 30th, 2016
Keeping the momentum up, here you have a calculator of the area and volume of a conethat will show you all the steps and formulas used to calculate the area and volume of a right circle cone radius \(r\) and height \(h\).

Calculator of the Area and Volume of a SphereNovember 30th, 2016
Another solver for our Geometry series, a calculator of the area and volume of a spherethat will show you all the steps and formulas used to calculate the area and volume of a sphere of radius \(r\).

Critical Correlation CalculatorNovember 29th, 2016
Typically found in special tables, here you have a critical correlation calculator. The advantage of this calculator is that it will compute the critical correlation for any value of \(n\), which is not always possible when you use critical correlation tables, which only have a few values of \(n\).

Polynomial Operations CalculatorNovember 25th, 2016
This one is a solver that user were clamoring for: Let me introduce our Polynomial Operations Calculator, with which you can add, subtract and multiply polynomials, with the solution shown step-by-step. Also, we have started with MathQuill, and excellent option for enhancing the input of math.

Absolute Value CalculatorNovember 23th, 2016
We expand even more our Algebra series with some more basic solvers, in this case, a absolute value calculator.

Fraction Operations CalculatorNovember 19th, 2016

Function GrapherNovember 17th, 2016
I have made a new function grapher to replace the old flash grapher we had. This time, I used the Google Chart format, that looks more modern and goes along the trend of JS charts.

Fraction ReductionNovember 13th, 2016
I get a lots of requests for this one, so here it goes. This is a fraction reduction tool fraction-reduction-lowest-terms.php, that takes a fraction into its lowest terms.

Next Algebra Solver in our seriesNovember 12th, 2016
This time, I added a greatest common divisor, or as it usually known as greatest common factor calculator . I took care to provide as much detail as possible in the calculations shown by the solver.

New Algebra SolverNovember 11th, 2016
Today I start with a new series of Algebra solvers. I have added a prime decomposition calculator, you type in a positive integer number and the solver tell you in a detailed way what is its prime decomposition.

Great changes to improve user experience are coming very soon. I have written recently many math and stats solvers that I'll be adding to the site. I've been polishing the scripts we already have and this is almost turning into a full time job. As many users are aware, we have had ads for the last few months, and even though I don't like ads, it is the only way to support the site, which is turning into a full time job by now. I'm looking for a more efficient way of using ads so that the site can be ad-supported and it continue being free that way.

Various Statistical TestsNovember 2nd, 2014
More stat tests done. I have finished a t-test for one population mean with unknown population standard deviation and a Chi-Square test for one population variance. Pretty much as the other solvers I have added, they are simple to use: define hypotheses, and parameters of the test, and a detailed step-by-step calculation is performed.

Histogram MakerOctober 20th, 2014
I just added a working histogram maker. You enter the dataset and the number of bins and a properly scaled histogram is rendered by the script.
